Does it make any sense (performance/relayibilty-wise? Ok , today I'm gonna install PBS on 4x2T (disks, not ssds) zfs raid10  and create one new dataset in /rpool  -> /rpool/databck    ...  So , the PBS itself and datastore will reside on the same pool ...  Then I'll make some copmarison tests (backup/restore)  and report back some relevant results  ...  I'd like to avoid PBS on its own pool because this SuperMicro 721 case has only 4 disk slots , a additional ones (2) have to be connected directly to MB ...
